Now the question i have are. Should the the functions be protected or public ?
If i want to have my extension controller independent from the model how can i do this.I mean in the actionDefault instead of Foo() and general when i need something like Foo::model() what can i use instead of it?
Last but not least.
How can then use the CExtController to be extending some controllers under Controller? should i use somethign like require_once?
